4WD Accessories & Auto Parts eCommerce Development
Selling 4WD and 4x4 accessories online has a problem most web developers never see: every product only fits certain vehicles, and most sales run through a dealer network. Get fitment wrong and you end up with returns, warranty arguments, and staff answering the same "will it fit" call all day. Get the dealer side wrong and your network learns to ignore the leads the website sends them.
I have spent years building for the 4WD accessories industry. The dealer ordering portal for East Coast Bullbars, Australia's leading alloy bullbar manufacturer, has processed over $90 million in online orders, fully synced with their ERP. The alloy wheel catalogue and dealer quote platform for ROH Wheels serves over 20 million requests a month, with a fitment engine covering 1,000+ vehicle configurations and a verified quote funnel feeding their dealer network across Australia and New Zealand. I have also built the All 4 Adventure competition websites since 2017, handling millions of entries from the Australian 4WD community.
Vehicle selectors, fitment recommendations, dealer quotes, ordering portals, and the Klaviyo and ERP integrations behind them: it is all work I have already shipped for brands in your industry.
You’re in good company
Why choose me for your next 4WD Accessories eCommerce project
Vehicle selectors with real results
Customers pick their year, make and model and see only what fits. The ROH Wheels platform runs a fitment engine covering 1,000+ vehicle configurations, and East Coast Bullbars customers search by vehicle or part number. No more guessing from a compatibility PDF.
Personalised fitment recommendations
Selecting a vehicle sets a context that follows the customer through the whole catalogue: live fitment badges with recommended, aggressive, and not-recommended states, options that do not fit hidden by default, and vehicle-specific product pages with tailored specs, imagery, and pricing at their own URLs.
Verified dealer quote funnels
When you sell through dealers, a quote request is your conversion. On ROH Wheels the customer's wheel and vehicle are prefilled, a local dealer is chosen on a map, and every lead is verified with a one-time PIN by SMS or email before a dealer is notified, so the network only ever receives real, consented enquiries.
Dealer ordering portals
The East Coast Bullbars dealer portal has processed over $90 million in online orders. Dealers see their own pricing, real-time stock, order approvals, and invoice history, all synced with the internal ERP, so orders stop arriving by phone and fax.
Find-a-dealer maps & dealer analytics
Map-based dealer finders with radius search across Australia and New Zealand, plus dashboards that track how quickly each dealer responds to the leads they receive, scoped to verified enquiries only, so you can manage the network on data rather than anecdotes.
Klaviyo & marketing integrations
Verified quote leads subscribe to the right regional Klaviyo list automatically, and a structured data layer feeds Google Tag Manager, GA4, and Meta Ads, so high-intent visitors can be retargeted and campaigns measured against real dealer leads.

Built by someone who knows fitment, dealers, and the 4WD industry.
A typical agency
A generic store with a vehicle dropdown.
-
Fitment is a tag-based filter bolted onto a theme, so customers still order products that do not fit their vehicle.
-
Quote forms are open to bots, and dealers learn to ignore the junk leads the website sends them.
-
The dealer network is a static store locator page that tells you nothing about what happens to a lead.
-
Pricing and stock are keyed in by hand and drift out of date within weeks.
-
The site falls over the first time a TV spot or paid campaign sends real traffic.
-
After launch the agency moves on, and the platform stagnates until the next expensive rebuild.
Working with me
Fitment, dealers, and ERP done properly.
-
A real fitment engine models diameter, width, PCD, and offset per vehicle, with clear recommended and not-recommended guidance, so customers and dealers stop guessing.
-
Quote funnels are rate limited, bot protected, and PIN verified before a dealer is notified. Dealers only ever receive real, consented enquiries.
-
Map-based dealer finders with radius search, plus analytics on how quickly each dealer responds to leads, so the network gets managed on data.
-
Products, pricing, stock, customers, and invoices sync with your ERP automatically. The East Coast Bullbars portal has run this way for years.
-
ROH Wheels serves over 20 million requests a month under heavy advertising spend, on caching and hosting I engineered and tune myself.

I have partnered with East Coast Bullbars and All 4 Adventure since 2017. The same developer who built the platform keeps improving it.
Website Project Process
Common 4WD Accessories eCommerce Project Questions
Can you build a vehicle selector for our 4WD accessories website?
Yes, this is a specialty of mine. A year, make, model (YMM) selector narrows the catalogue to what genuinely fits your customer's vehicle, not just what shares a tag. On the ROH Wheels platform a fitment engine covers 1,000+ vehicle configurations with recommended, aggressive, and not-recommended states, and East Coast Bullbars customers search by vehicle or part number.
We sell through dealers, not direct. Can the website still drive sales?
Yes, and this model is where I have done my strongest industry work. For ROH Wheels the website converts catalogue browsers into verified quote requests, prefilled with the customer's wheel and vehicle and routed to their nearest dealer, with every lead verified by a one-time PIN over SMS or email before the dealer is notified. You get qualified leads for the network and clean data on how each dealer responds to them.
Can our dealers order online instead of phoning orders through?
Yes. The dealer ordering portal I built for East Coast Bullbars has processed over $90 million in online orders. Dealers log in to their own pricing, real-time stock, order approvals, and invoice history, and everything syncs with the internal ERP so nothing is rekeyed by your staff.
Does the website integrate with our ERP?
Yes, and this is usually where the real value is. Products, pricing, stock, customers, orders, and invoices sync between the website and your internal system, using scheduled and real-time updates so the site always reflects reality. The East Coast Bullbars portal syncs thousands of ERP rows every day and has done so reliably for years.
Can you integrate Klaviyo for our email marketing?
Yes. On ROH Wheels, verified quote leads are subscribed to the correct regional Klaviyo list for Australia or New Zealand automatically, so the marketing team can run flows against genuinely consented, high-intent subscribers. A structured data layer also feeds Google Tag Manager, GA4, and Meta Ads for retargeting.
What happens when a TV spot or paid campaign spikes our traffic?
The platforms I build are engineered for it. ROH Wheels serves over 20 million requests a month under sustained advertising spend, and the All 4 Adventure competition sites have handled millions of entries alongside a national TV telecast. Caching, queueing, and hosting are tuned by hand so spikes are absorbed rather than survived.
